A 72-year-old woman with a diagnosis of suspected rheumatoid arthritis was admitted with multiple pulmonary nodules in the bilateral lung field. To obtain a diagnosis, a nodule was resected using video-assisted thoracic surgery. Microscopically, amorphous eosinophilic acellular substances were surrounded by inflammatory infiltrates, which were confirmed to be amyloid deposits by congo red staining. Thus, a diagnosis of pulmonary amyloidosis was obtained. The clinical features and diagnostic process are discussed.
一名72岁女性，诊断为疑似类风湿性关节炎，因双侧肺野多发肺结节入院。为明确诊断，采用电视辅助胸腔镜手术切除了一个结节。显微镜下，无定形嗜酸性无细胞物质被炎性浸润包围，刚果红染色证实为淀粉样沉积物。因此，确诊为肺淀粉样变性。本文讨论了其临床特征和诊断过程。
